`FRED R. CUTLER, and JAMES D. JOHNSTON,

citizens ofthe United States,`residing at Kansas City, in the county 'of Jackson and State of Missouri, have invented certain new andl useful Improvements in Stoves, of which the following is a specification.

Ourinvention relates to improvements in stoves. l

The object of our invention is to provide a construction of stove having novel means for conducting air from adjacent the floor.

Application led April 4, 1905. Serial No. 253.936.v

The upper half *f of the base is secured to the upper side of the the'partition 6 are provided one or more w openings 7. The upper-side of 'the upper l halfoi1 the base is'provided outside the openings 71with an annular liange 8. Mounted on the upper half oi the base above the ashboX isv the iire-pot 9, in the upper end of which is provided an annular groovei10, in which isfitted the annular vertical flange 11, projecting downward from 'the under side of a horizontal lower ring 12, the upper sideof which is provided' witha vertical annular flange 13, over which is fitted the lower end of a vertical tubular drum 14. Upon the vring 12 is clamped an upper ring 15, between.

which and the ring'12 is disposed a horizon-V tal'peripheral Viiange l16, provided on the lower end ofthe drum 14. The drum 14'has fitted into its4 upper end a horizontal cap 131i lower tubular jacket 19 has its lower end iitte'd overthefiiange .8 of the baste, thefupper l end of the jacket being fitted over the periphery of'the'rin'gl12.

lThe openings 7 communicatewith the annular space provided between the jacket 19 and the fire-pot 9,'v which the jacket encircles.

The upper Side' of the' ring 15 is provided with` a vertical annular flange 20, in which is iitted the'l'owe'r end oil an upper tubular jacket 21,

the upper end of which-is'tted over` a vertical annular flange 22j provided on thelower side of `a horizontal ring'23, which encircles the drum v1 4. The ring 1 2 is provided outside the fire-pot'v 9 and insidethejacke't 19 with'onel or morev openings 24, which communicate withthe an- Ioo.

nularspace between the fire-pot 9 and jacket f 19. The ring' 15A-'isf provided vbetween the drum 14 and jaeket 21 withone or more openings y25, which register withthe openings 24 and communicate with the 'annular space provided between the jacket 21 and the drum' ,side diameter of the ymember 28.

'- door 18 with a vertical opening registering Withthe opening in a vertical air-tube 26, the yupper'end of which is secured to the under side ofthecap 17.and the lower end of which .-is provided with a horizontal k*peripheral flange 27, fitted in van annular groove provided on kthe inner side of the upper end of a ,bell- .shaped vmember 28, which comprises, preferably, two vertical halves, each having oppositely-.disposedlateral lugs 29, .secured to the oppositel-y-disposed lugs of the other half by bolts 30. la vertical tubular bell -sha-ped deflector 31, havingzanoutside diameter less than the in- .flector 31 has a plurality of radial larms 82,' -whichrestinan annular groove 33,provided Yin the -inner wall ofthe member 28. The lower-end of the jmember 28 is disposed above fthe-fuel placed in the fire-pot 9. Air passing downward through the tube 26 will pass through the member 28, part going inside the .deflector 31 anda ypart passing outside the deliector. The air will thus be diffusedevenly roverthe fuel. To have the air pass out of the member 28 with considerable force, .the ,annularspace between .the outside the derflector and the Amember 28 `may be narrower at the lower than at its upper end.

Upon the upper side of the cap 17 is slid- `ably mounted aplate 34adapted when properly positioned -to have its inner 'end Icover the opening in the `top of the cap over the .tube 26. The plate 34 -is ,provided with one or more vertical holes where the plate covers .the opening .in the=cap 17 to permit the passage oflair through the plate and into the Aairltube 26. To the yupperfside ofthe plate 34 is pivoteda horizontal plate 35, provided with vonelor moreopenings 36, adapted to register with vthe holes in the plate 34. To fully uncover .the upperendofthe tube 26, the plate 34 is pulled outward .the yproperldistance. If `it is desired yto vary the amount ofairenter- .ingthe 4tube 26-by ,turning the plate '35, this vmay be done instead 4of withdrawing `the plate34.

.Our invention may be modified in many Ways without departing from its spirit.
